I believe Yodel drivers are regularly found standing in people's porches writing out the "could not deliver" note - a side effect of the payment structure, as I understand it, in which they are paid the same for attempted deliveries as actual ones.

I vaguely recall that sketch and yes, I think it was Smith and Jones (either them or Not the 9 O'Clock News). Anyway I've now established no one will do anything until Monday afternoon.
